PLATFORM FOR HOD-ELEVATORS.

Specification of Letters Patent.

Patented Dec. 30, 1919.

Application filed April 11, 1917. Serial No. 161,345.

To all whom it may concern:

Be it known that I, CHARLES WV. ANDER- SON, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Platforms for Hod-Elevators, of which the following is a specification.

This invention relates to an improved platform for hod elevators or the like.

The object of the invention is to provide a simple, durable and efficient platform device adapted to move with the elevator chain for conveyance of articles of different descriptions, such for instance as a bucket, building blocks, or the like.

A further object is to so construct the de vice as to provide retaining flanges at all appropriate points, and to arrange certain of the retaining flanges to constitute stiffen ing elements for the device to the end that maximum strength is obtained from a minimum weight of material.

A. further object is to so arrange the parts of the device that the device may be readily connected to or disconnected from the elevator chain at will, so that when disconnected the parts will lie in a compact and easily transportable condition.

Other objects and aims of the invention, more or less specific than those referred to above, will be in part obvious and in part pointed out in the course of the following description of the elements, combinations, arrangements of parts and applications of principles, constituting the invention; and the scope of protection contemplated will be indicated in the appended claims.

In the accompanying drawings which are to be taken as a part of this specification, and in which I have shown merely apreferred form of embodiment of the invention:

Figure '1 is a vertical transverse sectional view of a platform device constructed in accordance with this invention, said section being taken substantially upon the plane of line 1 of Fig. 2, and illustrating the platform in position upon an elevator chain;

Fig. 2 is a top plan view of the structure shown in Fig. 1, partsbeing illustrated in horizontal section substantially upon the plane of line II of Fig. 1.

Fig. 3"is a side elevational view of the platform as it appears on the down lead of the chain.

"Fig. '4. is an enlarged fragmentary detail dicated in sectional view taken IV of Fig. 2.

Fig. 5 is a similar enlarged plan view of the parts shown in Fig. 4, a portion of the structure being broken away and illustrated in section.

Fig. 6 is an enlarged fragmentary elevational View illustrating the manner of conneilting the brace rods to the elevator chain, an

Fig. 7 is an enlarged fragmentary plan view, partly in section, showing the manner of connecting certain of the parts.

Referring to the drawings for describing in detail the structure which is illustrated therein, the reference character L indicates the up lead of an elevator chain and G the down load thereof. The platform comprises a horizontal part H and a diagonal brace part A, the horizontal part being connected by its inner end to the chain and the diagonal brace part extending from the outer end of the horizontal part diagonally inwardly to the chain. As illustrated in the drawing the diagonal brace part A extends upwardly from the horizontal part on the up lead of the chain and downwardly on the down lead of the chain. The diagonal brace part extends upwardly on the up lead of the chain for the reason that the platform usually carries more of a load when ascending than when descending and the brace part constitutes an efiicient guard for the load as will be presently apparent.

The horizontal part H is made up of a pair of side members 1 and 2 spaced apart. Their outer ends are connected by means of a tie rod N and their inner ends are slotted as at 3 to engage one of the cross bars 4 of the chain. The slots 3 extend inwardly from the ends of the members 1 and 2 and latch members 5 are arranged for engaging the cross bars to retain the slots 3 in position over the cross bar. These latches 5 are pivotally connected to the side members 1 and 2 as at 6, the pivot being substantially in line with the longitudinal axes of the slots Each latch has a slot 7 formed therein at its free end for engaging the cross bar. The slots 7 are arranged at right angles to the slots 3,'that is transversally of the length of the latches. This arrangement is clearly in- Fig. 1. When the latches are swung, downwardly to engage over the cross bars wall parts 8 stand to engage the cross upon the plane of line bar to positively close the open ends of the slots 8.

Any suitable means may be employed for retaining the latches in latching position.

The means illustrated comprises thumb. screws 9 which have threaded engagementwith thelatches and are adapted to be moved,

into and out of engagement through openings 10 formed in the side members 1 and 2. The threads upon the end portion ofthe screws are preferably mutilated as indicated at 11 so as to prevent entire displacementof the screws from the latches while yet permitting introduction and removal from the openings 10.

A base plate 12 of sheet metal or thelike is supported between the side members 1 and 2. This base plate has side flanges 13,.which are connected to the side members 1 and 2 preferably by rivets 14;.- A flange 15 is formed along the outer end edgeof thebase plate and a double flange 16-17 {is formed along the inner edge of the baseplate- As 'viewed in Fig, 1 the flange 15 is turned downwardly and the main flat portion of the base plate stands in a horizontal plane of the tie rod N so thatsaid tie rod serves in effect, as a flange or barrier the flat upper surface of the with relation to base plate to prevent likelihood of articles sliding off of the forward edge of the base plate. Thisis important, as it will be seen from comparison with Fig. 3 that the flange 15 is left to project vator moves to the down lead of the chain. The tie rod N thus serves a double purpose of connecting parts together and all serving as a guard member.

The double flanges 16 17 at the rear edge of the base plate mutually strengthen the structure and serves equally well as a guard member whether upon the up lead or the down lead of thechain;

The diagonal brace part A is made up of two members, as 18 and 19 spaced apart and disposed one adjacent each of the side members 1 and 2. As viewed in Fig. 1, the lower ends of the members 18 and 19 are pivotally connected to the outer ends of the members 1 and 2 by means ofthe tie rod-N. The details of the pivotal connections are clearly, shown in Fig. 7 in which figure theside member 1 and the brace member. 18 are shown to have mating apertures 20 therethrough through which the tie. rod extends, a nut or the like as 21 beingconnected to the outer. end of the tie rod.

The upper ends ofthebraces 18 and 19- are connected to one of the crossbars Lot the chain in a manner similar to that .de-. r bed, orthes e me be .111 J-' he. details of he parts at theupper ends .of the. braces 18 and 19 for making connections. t theme-re. e in ig- 6 i hicht v ferents mer ls 2 i d cat a l h:

upwardly whenthe eleby. the latchfor engaging. in an aperture 25 in the same manner as described with reference to the-latch 5. The end portion of the member 18 is provided with a slot 26 .which extends diagonally from the under edge of the member. The latch 22 is formed with a diagonal slot 27 which is similar to the slot 26 exceptthatthe slot 2? 12111311618. into the latch from the upper edge. In connecting these parts with the cross bar of the chain the cross bar. is simultaneously induced into ,the slots 26.-27, the latches automatically moving to bring the thumb screws 27 into alinement with theopenings 25 as the cross bar reaches the ends of the slots. There-is no tendency tor-thewcross rods to move out of the slots when the platform is upon'the up lead of the chain and the engagement. of the thumbsri ews with the apertures'25 will prevent movement. of the; latches and thereby prevent displace ment of the cross rod when the platformis on the. down leadof the chain.

It is obvious from the above description that the device may be readily attached to orremoved .from the chain at will and that, by reason of the pivotal connection of the. brace members 18 and 19, with theside members 1 and 2 said brace members are free to swing substantially into parallelism, with the-side members 1 and-.2 when detached from the chain thus producing a contracted arrangement of the parts at such timesas the device, isnot connected with the chain.

The side members 1 and- 2 may be formed with extensions 28 if desired .saidextensions being attacheld to serve as stiffening means and to constitute suitable guard means for any article carried bythe platform whileon the .downi. lead of the. chain.

Althe'ugh the drawing illustrates the, side members of the platform to be formed with oiiset, portions as 29. it;will be understood that thisis only, an expedientto accommodate a. given sizeof platform to a given width of elevator chain and may bean offset in either, direction or may be omitted entirely.

As many construction without; departing from ,the scope,oftheinvention as defined in the followingclaims, it is intended that all mat ter contained in theabovefl description or shown ,in the accompanying drawings, shall be interpreted as illustrativeonly and not in a limiting sensei-g Having thus described my invention what I claim as new and desire to obtain, by Letters Patent is:

1. A platform for hod ,elevators or the like omp sing o y member n b ce m m: her, and means connecting said members-to gather constit ng a ard m mb r. e
